Hi all,
I have an 80 Gig hard drive with the following partition layout:
Primary 1 - MS-DOS - 29996 Meg
Extended with 1 Logical drive (D) - MS DOS - 27996 Meg
FreeBSD Partition - 20167 Meg
I'm trying to mount the extended partition. My primary dos partition is
/dev/ad4s1
I've tried mounting the extended as follows:
mount_msdos /dev/ad4s2 /mnt/dose
mount_msdos /dev/ad4s2a /mnt/dose
mount_msdos /dev/ad4s2b /mnt/dose
mount_msdos /dev/ad4s2c /mnt/dose
mount_msdos /dev/ad4s2d /mnt/dose
All of these return with
mount_msdos: /dev/ad4s2x: Invalid argument
Any ideas on how I mount this logical drive in this extended partition ?
For the record, fdisk ad4 presents the following output:
# fdisk ad4
******* Working on device /dev/ad4 *******
parameters extracted from in-core disklabel are:
cylinders=9964 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=9964 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 12,(DOS or Windows 95 with 32 bit FAT, LBA)
start 63, size 61432497 (29996 Meg), flag 0
beg: cyl 0/ head 1/ sector 1;
end: cyl 1023/ head 254/ sector 63
The data for partition 2 is:
sysid 15,(Extended DOS, LBA)
start 61432560, size 57335985 (27996 Meg), flag 0
beg: cyl 1023/ head 255/ sector 63;
end: cyl 1023/ head 254/ sector 63
The data for partition 3 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 118768545, size 41303115 (20167 Meg), flag 80 (active)
beg: cyl 1023/ head 255/ sector 63;
end: cyl 1023/ head 254/ sector 63
The data for partition 4 is:
<UNUSED>
Thanks in advance,
